摘　　要：针对当前基于中间件负载平衡机制中负载定位不够准确、监测粒度过大等问题,基于模糊逻辑技术提出一种更精确、更细粒度的负载平衡系统及其负载平衡机制。负载平衡系统的节点负载信息记录表记录系统中所有节点从模糊推理得出的负载状态信息,负载转发表记录服务节点与相应服务请求者之间的关系。实验结果表明,该负载平衡机制能有效地定位过载节点,较好地实现集群中的负载平衡服务。Aiming at the problem of the inaccurate information in the monitoring based on the current middleware load balancing mechanism,and of the large size of the particle,this paper designs a more precise,more fine-grained load balancing system and its associated load balancing mechanism with the combination of fuzzy logic technology.Record list of load information records load state information,and load transfer list records relationship between service nodes and service requesters.Experimental result shows that the load balancing mechanism can effectively target node overload to better achieve load balancing system services of the cluster.
